SURFACE CONDENSER.

. Application led May 8,-

` To 'all whom it may concern.'

Be itknown that I, LUTHER' D. LQVEKIN, a citizen of the United States of America,

' and residentl of Ardmore, county of -Montgomery, State of Penns lvania, have invented a certain new an useful Improve- Ament in Surface Condensers, of which the following is a true and exact description, reference being had to the accompanyingdrawings, which form a part thereof.

My invention'relatesto surface condensers and has for its object particularly to provide a condenser from each lateral half of which the cooling Water can be cut oit at will to permit of the cleaning of the tubes and which, in addition to high etiiciency when in full use, will work with very great efficiency `when the cooling water is cut ofi from half of the tubes.

The nature of my improvements will be best understood as described in connection with the drawings in which they are illusf trated and in which Figure 1 isa sectional elevation of my improved condenser take on the line 1-1 of Fig. 2.

Figure 2 is across sectional View on the line 2 2 of Fig. 1.

Figure 3 is a horizontal section inthe line 3-3 of Fig. 1.

Figure 4C is a sectional elevation taken on the line 4-4 of Fig. 1, and

Figure 5 is a sectional elevation on the line 5-5 of Fig. 1.

A indicates the shell of the condenser formed so as to provide lateral Vertical bypasses lindicated at A', A. A2 indicates the opening for the entrance ot steam at the top oi" the shell, A3 the opening at the bottom of the shell for the outlet of condensed water, and A4L openings through the ends of the shell for the outlet of air. B is a bank of horizontal tubes located inthe upper section of the shell extending, as a belt across the shell but not into the lateral by-pass indicated at A, A', as shown, and preterably1 the upper tube belt B Ais divided into Sections indicated at B, B', etc. by vertical steam lanes, indicated at C, C, etc. These steam lanes extending, as shown, throughout the depth ot the belt though, obviously, they need not extend entirely through the belt. D, D, indicate the lower group of tubes spaced from the sides of the shell by passages F, F, in free communication with the by-passes A. Through the center of the 1923. Serial No.` 637,442.

lower tube group extends the air outlet casling G having openings G for the entrance of air and communicating with the chamber Grzfrom which the air escapes to the air ump, not shown, through the openings A4.

form the tube groups D, D, with horizon tal steam lanes indicated at C', which1 in this construction, should not extend entirely through the tube groups but i', etc. I

terminate some distance short of the air casing G, as shown. Th-e passages F are conA tinued, as shown, by contracted passages F 2 leading into chambers F3 at the bottom of the tube group D, D.

H, H, are dampers provide-d for opening and closing the lateral steam by-passes iudicated at A. They are secured ou shafts H and operated by levers H2 which are held in adjusted positions by the pins on segments H3. I is a head secure-d at one end of the casing anddivided into four chambers K, k, K, 7c', by the partitions I and I2. I3, I3, are openings for the admission ot water to the chambers K, 1, and I4, I4, are passages for the outlet of water trom the chambers K', Z2. On the opposite end of the shell is secured the header J divi-ded into two chambers L and Z by the partition J.

In normal operation, water is admitted through both water passages I3 into the chambers K and 7c, from which it passes through the tube groups D, D, into the eliamcirculates through one ylateral half oi the.

condenser and the damper H on this half of the condenser is open so that a portion of the steam will pass through/the controlled ley-pass Af into `the chamber F without passing through the tube groups B. The by-pass, of course, must be of such regulated size as to insure that when open it will not take all of the steam but only such portion thereof as can be properly condensed in the tube group D through which waterl is passing. The air and any uncondensed steam passing through the tube groupsB into the passage F mixes with the uncondensed steam passing through the by-pass A into the chamber F and its continuation F2, F3, and

the air and steam is drawn through the core,

`group but also defines the passages' F, F,

through which the steam and air passing thrugh the upper tube group is guided, into the lateral passages or chambers F.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

shell, a rain plate situatedbetween the upper at will.

1. A surface condenser comprising in combination a shell, a group of horizontal tubes extending in a belt across the upperlpart of the shell and constituting'the primary condensing zone, a second groupof horizontal tubes arranged in the lower part of l the and lower tube groups, an air outlet casing located in the lower tube group, one by-pass leading from the top of the shell to the lower part thereof whereby a portion of the steam can bel led directly to the lower group of tubes without passing through the upper group, a damper' for opening and closing the by-pass, and two separate means fo-rpassing `cooling water through the upperv and lower tube groups' whereby the watercan be cut ofi from either lateral side of the condenser 2. Asurface condenser comp-rising in ,combinationa shell, a group of horizontal tubes extending in a belt across the upper part of the shell and constituting the primary condensing zone, a second group of horizontal tubes arranged in the lower part of the shell, a

rain :plate situated between the upper and lower tube groups, an air outlet casing 1o-a cated in the lower tube group, two by-passes zontal tubes extending in a belt across the upper part of the shell` by-passes for steam formed between the side walls of the shell and the upper horizontal belt of tubes dampers for opening and closing said bypasses at will, a lower group of tubes spaced from the side walls of the shell, an air exit casing located centrally in said lower group of tubes, a rain plate located between the upper and lower tube groups and two separate means for passing water through the upper and lower tube groups whereby the cooling water can be cut oil from either lateral side of the condenser at will.

4. A surface condenser comprising in combination a shell having an opening for the entrance of steam at its top', a group of horizontal tubes extending in a belt across the upper part of the shell, said group having Vertical steam lanes formed therein, by passes for steam formed between the side walls of the shell and the upper horizontal belt of tubes, dampers for opening and closing said by-passes at will, a lower group of tubes spaced from the side walls of the shell,

said tube group having horizontal steam lanes formed therein, an air exit casing located centrally in said lower group of tubes, a rain plate located between the upper and lower tube groups and two separate means for passing water through the upper and lower tube groups wherebythe cooling water can be cut off from either lateral side of thc condenser at will. t
